Title: Power transmission device
Inventor: MASUYAMA AKIHIRO
IPC: F16D35/00
Filed: 1987-04-08
Abstract: PURPOSE:To make a device small-sized by providing a power transmission device serving as a center differential device of a 4WD vehicle with an actuation chamber for limiting the differential movement of the differential device and an actuation chamber for absorbing difference in rpm between front and rear wheels. CONSTITUTION:A differential device 33 is interposed between a left side wheel drive shaft 31 and a right side wheel drive shaft 32 for smoothly performing a turning driving and others. A 1st actuation chamber 47 for controlling the differential movement between the right and left wheel shafts and a 2nd actuation chamber 48 for allowing the differential movement between the front and rear wheel shafts and for automatically changing power transmission ratios between the front and rear wheels are communicated to each other. As a result, if silicone oil in either of the actuation chamber 47 and 48 expands, the expanded oil flows to the other chamber so that pressure rise in either of the actuation chambers 47 and 48 can be prevented. As a result, a mechanism of a viscous coupling can be simplified.

Title: Robot controller
Inventor: TAMURA KINICHI
IPC: B25J9/16
Filed: 1985-04-22
Abstract: PURPOSE:To make a smooth following-up operation possible for robot damping control by providing a command value control circuit which sets a command value based on the deviation between a speed command value and a speed feedback value to zero, a compensating circuit, and a speed limiting circuit. CONSTITUTION:When a relay coil L1 is excited, movable contacts (c) of changeover switches SW1-SW11 are switched to fixed contacts (a) and a command value control circuit 45 sets the speed command value and the speed feedback value, which are inputted to speed control parts 26 and 36, to zero. When contacts of switches SW1 and SW2 are switched to contacts (a), signals G1 and G2 from a speed limiting circuit 70 become zero, and a current command value S1 from the control part 26 becomes zero, and a motor 10 becomes free therefore to break the attitude of a moving part. For the purpose preventing this attitude break, a current control part 27 flows a driving current corresponding to a compensation command value CS1 inputted form a gravity balance compensating circuit 50 to a motor 4, and the balance is kept by its generated torque.

Title: Crusher for pavement and support thereof
Inventor: DEIBITSUTO TOMUSON ARAN
IPC: B25D17/24
Filed: 1990-04-02
Abstract: PURPOSE: To prevent vibrational forces produced by the reciprocation of a breaker housing from working on its handle so as to reduce the degree of fatigue of an operator and to increase the effective speed of a tool operation by resiliently coupling the handle to an operating chisel. CONSTITUTION: A handle 18 and a chisel 12 in a breaker 10 are resiliently coupled to each other via a rubber bushing 24 to interrupt the interaction from the breaker 10 to the handle 18. Therefore when the chisel 12 makes contact with a workpiece 14 and stays in a relatively stationary condition, a breaker main body makes a vertical reciprocating movement. Therefore, an operator is isolated from a principle source of vibration.

Title: Interchange type rewritable optical disk
Inventor: UCHIUMI KENICHI
IPC: G11B7/243
Filed: 1988-04-08
Abstract: PURPOSE:To obtain the rewritable optical disk which allows reading out with a reproduction-only player by providing grooves to the surface of a disk substrate and previously increasing the reflectivity of the peak parts between the recesses at the time of recording or reading out information along the recesses of the grooves. CONSTITUTION:A recording film 13 is formed by vacuum vapor deposition of, for example, In and Sb on the grooved substrate 11. The initial reflectivity of the disk is about 40% in the flat part. The reflectivity increases to about 60% when the disk is irradiated by strong laser beam pulses. In succession, when the disk is irradiated by the weak laser beam, the reflectivity returns to the initial value of 40%. Rewriting is, therefore, possible if the high reflectivity state is used as a recording state and the low reflectivity state as an erasing state. The reflectivity is increased to about 1.5 times by rotating this disk and causing the peak parts to be irradiated by the laser beam. The disk recorded with the information in the prescribed format in the groove parts 12 allows reproduction with the reproduction-only player as well.

Title: Air-fuel ratio controller for lean combustible internal combustion engine
Inventor: GOTO MASAHITO
IPC: F02D41/14
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To achieve matching of low fuel consumption (low CO2 exhaust am ount) and low NOx exhaust amount which are contrary each other considering environmental protection, by prohibiting lean operation depending on NOx concentration in the region where a vehicle is now running. SOLUTION: A device on an electric beacon 87 side measures NOx concentration in sampled atmosphere, sends a lean operation prohibition signal when the NOx concentration is more than judging criterion, and sends a lean operation permission signal when the NOx concentration is less than judging criterion. An electronic controller 90 of a lean combustible engine 1, when it receives the lean operation prohibition signal, prohibits lean operation even in operation condition that lean operation can be performed, and performs stoichimetric operation, therefore NOx exhaust amount is restrained.

IPC: C06C7/00
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a gunpowder cartridge holder having filter effect by preventing grinds and fuel residues from being discharged to the outside without lowering gas pressure. SOLUTION: A sleeve 6 and a retainer 7 are fixed in the state where there is ensured a gap for forming a cavity part 9 and a flow passage 10 in a cartridge holder 5, and a slit 11 is formed in the retainer 7 for guiding gas from the flow passage 10 to a piping. In the cartridge holder with the above construction grinds produced following explosion of a gunpowder cartridge C fall in the cartridge holder 5 owing to their self-weights, and light weight grinds are obstructed by an inside surface of the retainer 7 forming the slit 11 and hence are prevented from being discharged to the outside from the inside of the cartridge holder 5. Thus, filter effect is exhibited, and pressure is prevented from being reduced because a transmission passage for gas pressure is largely secured.
